FREDERICK B. COLE, OF LONGB EACI-I, CALIFORNIA.

concnmn-srrin'enn MOLD.

Application filed January 23, 1913.

To all whom itmay concern Be it known that I, FREDERICK citizen of theUnited States, residing at Longbeach, in the county of Los Angelcs andState of California, have invented certain new and useful Improvementsin (loncrete-Shingle Molds; and I do declare the following to be a full;clear, and exact description of the invention, such as will enableothers skilled in the art to which it and use the same.

This invention relates to improvements in concrete shingle molds.

One object of the invention is to provide a shingle mold by means ofwhich shingles may be formed directly on a root and in separate orindependent courses thus providing for the Contraction and expansion ofthe shingles without injuring the roof structure or cracking theshingles.

Another object is to provide a mold of this character whereby thesuccessive independent courses of shingles may be formed without waitingfor the previously laid courses to set or harden.

With these and other objects in view, the invention consists of certainnovel features of construction and the combination and arrangement ofparts as will beniore fully described and claimed.

In the accompanying drawings; Figure 1 is a perspective view of aportion of a root showing-the manner in which the shingles are formedthereon by my improved mold; Fig. 2 'isa similar view illustrating onone portion of the root the finished courses of shingles and on theother portion of the roof illustrating the molds still in positionthereon; Fig. 3 is an enlarged vertical soctional view of a'portion of aroot illustrating the operation of forming the shingles thereon with myimproved mold; Fig. 4: is a top plan View of a portion of one ottheshingle forming boards of the mold; Fig. 5 is an edge view perspectiveview of one of the fastening rods for the shingles.

My improved shingle mold comprises a board or plate 1 of suitable widthand length, the width of the board 1 being slightly greater than thelength of the exposed parts of the shingles formed thereby. On the upperside of the board 1 are secured transverse cleats 2 which are of lesslength than the width of the boards and which terminate at the upperends thereof a short B. Conn, a

dis-truce from the upper edges of the boards as clearly shown in 3 and4c of the drawing. The cleats when thus arranged form stops to -supportthe boards when arranged for 'l'orniing the successive courses ofshingles.

Secured to the lower side of the board 1 are a series of crease formingstrips 3 which are spaced equal distances apart the spaces between thestrips corresponding to the width of the shingles. slightly less lengththan the width of the boards 1 and terminate above the lower edges ofthe boards a distance corresponding with the distance the boards overlapeach other when arranged for forming the successive courses of shinglesas clearly shown in Fig. 3 of the drawings.

In forming a root and covering the same uith my improved shingles thesheathing boards 4.- are laid on the rafters in the usual manner andalong the lower edge of the lowermost sheathing board is laid a spacingstrip 5 to which secured a narrow strip (3 for forming the lower end ofthe lowermost courseot shingles and which supports the lower edge of themold board l for the first course of shingles asclearly indicated inFig. 3 of the drawings. After the strips 5 and (3 have been temporarilysecured to the rafters at the lower edge of the sheathing boards a theusual or any suitable form of tar or waterproof paper or felt 7.Arranged at intervals on the paper 7 a suitable distance above the loweredge or the root or above the bottom strip (3 are a series of V-shapedshingle fastening rods 8 the upper looped ends ot which are fastened by.staples t) or other suitable fastening lBVldQS to the sheathing boards 4as clearly shown in Figs. 1 and 3 o'l'the drawingsf A'lter the lowercourse of rods 8 have thus been arranged and secured, the cement orconcrete for forming the lower course 10 of shingles is placed on thewater proof papcr along the lower portion 01' the root and is troweleddown from the strip (3 to the desired thickness or taper as shown. Afterthe cement for the lower course 10 of shingles has thus been placed onthe roof and trowcled out one of the mold boards 1 is laid on the lowerportion of the cement, said board having its lower edgeresting on theupper edge of the bottom strip 6. When thus arranged the lower ends ofthe crease forming strips 3 on the lower side of the The strips 3 are ofi board in the same manner as tract to any board 1 engage or abutagainst the upper side of the bottom stri 6 and thus hold the in properposition for formin the upper surface of the first course of shinglesand the lower end of the next course. When the board 1 is thus placed-onthe cement the strips 3 are forced down or will embed themselves intothe upper surface of the cement and will form creases which will imitatethe usual crack or space which occurs between the wooden shingles of theroof. After the lower course of shingles have thus been formed a stripof tar or water-proof paper 1.1 is laid over the tapered upper portionof the cement forming the first course of shingles and which is exposedabove the upper edge of the board 1. After this sheet of tar paper 11has been laced in position another set of the shinge holding rods 8 arearranged over the paper and secured at their upper ends to the sheathingboards 4 described in connection with the lower series of fasteningrods. After the sheet of paper 11 and the second series of rods 8 havebeen arranged in position, the cement for the second course of shingles12, is placed on the paper and over the rods'and is troweled down fromthe u per edge of the board 1 to the desired thiciiness and taper afterwhich a second board -1 is placed on the lower portion of the cementforming the second course 12, the lower edge of this board resting onthe upper portion of the board forming the preceding course of shingles.When thus arranged the crease forming strips of the second board havetheir lower ends engaged with the upper edge of the board forming thefirst course of shingles, the lower edge of the board forming the secondcourse of shingles engages the upper ends of the cleats 2 on the upperside of the receding board and is thus supported and held in properposition for forming the top of the second courseof shingles and thebottom or lower end of the next course. The succeeding courses areformed in the same manner as the second course and a further descriptionof the formation of the successive courses of shingles is not thought tohemeessary.

In thus forming the shingles it will be noted that each successivecourse is entirely separate or independent from the other courses andthat in thus forming the courses they will be permitted to expand andconextent without injuring any part of the structural framework of theroof or cracking the shingles. By providing the fastening rods 8 it willbe seen that the courses of shin 'les are also secured to the sheathingboar s of the roof so that said courses have absolutely no connectionwith creasing mem each other except the loose overlapping engagement ofthe lower portions thereof, said overlapping portions being separated bythe sheets of tar or water-proof paper arranged between the same whilethe courses are being formed. It will also be noted that in constructingthe roof in the manner described, the successive courses of shingles maybe formed before the set or hardened and without danger of the cement ofone course becoming mixed with or joining the cement of the precedingcourse thereby permitting the construction of the shingles to be rapidlyand easily accomplished.

From the foregoing description taken in connection with the accompanyingdrawings the construction and operation of the invenpreceding courseshave tion will be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as claimed.

Having thus described my invention, what I claim is: I

1. In a shingle forming mold of the character described, the combinationof a series of mold boards adapted to be placed one above the other inoverlapping engagement, a plurality of cleatsfsccured to the u persurface of said boards'and adaptedto lmit their overlap ing engagement,a series of ers secured to the lower sur face of said boards to formcreases in the shingles, and means to separate the successive courses ofshingles thereby permitting.

said courses to be formed before the precediiYg courses'have set orhardened.

2. A shingle forming mold of the character described comprising a seriesof boards having to form supports for the boards of the successivemolds, lower sides of said boards and adapted to form creases in theshingles to represent cracks between the shingles, means to separate thecourses of shingles formed by one of the mold boards from the coursesformed by the preceding boards, and shingle fastening rods adapted to besecured at their u and to be embedded 1n per ends to the roof thecourses of shingles when the latter are formed thereby independentlyfastening the courses of shingles to the roof.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
